Chocolate is a compound that usually exists as a solid.  You’ve probably noticed that when you hold chocolate in your hand or try to eat it on a warm day, it gets soft and melts!  The high air temperature on a hot day, or your body’s heat increases the chocolate’s temperature until it changes from a solid to a liquid state.

Intoscience: Colour can alter taste perceptionEuropean scientists say they have found further evidence that how you serve food and drink matters hugely in the perception of taste.

Researchers at the Polytechnic University of Valencia and the University of Oxford recruited 57 volunteers and asked them to taste hot chocolate served in plastic cups with four different colours — white, cream, red and orange with white on the inside.

The chocolate was the same in all the samples, but the volunteers found that the flavour was better when the drink was served in the orange or cream-coloured cups.

Colour enhances taste and aroma

“The colour of the container where food and drink are served can enhance some attributes like taste and aroma,” Betina Piqueras-Fiszman of the Polytechnic University of Valencia said in a press release. The findings could be beneficial to chefs and food manufacturers, Piqueras-Fiszman added.

Previous research has found that yellow containers boost the perception of flavour of lemons in soft drinks; beverages with cold colours, like blue, seem more thirst-quenching than warm colours like red; and if
drinks are pink, they are perceived as being more sugary.
